Holt Castle stands on the west bank of the River Dee in Wrexham, Wales, built between 1282 and 1311 by John de Warren. This strategically important Norman fortress featured distinctive round corner towers and was constructed from locally quarried triassic sandstone. The castle served as an English stronghold after Edward I's conquest of Wales and withstood two sieges during the English Civil War, becoming the final castle to fall in Northeast Wales in 1646. Though substantial stone was removed in the 17th and 18th centuries for nearby construction, visitors can observe remains of the defensive walls, gateways, moat traces, and weathered stonework protruding from the grassy mound, along with the castle's earthen defenses.
